In plate girder, Stiffeners are the members provided to prevent:
- Compressive stresses
- Tearing failure
- Web crippling
- Buckling of web plate
Answer: D. Buckling of web plate
In plate girder, stiffeners are the members provided to prevent web buckling.
Solution
Stiffeners are the members provided to prevent buckling of web plate.
- These stiffeners can be found in both transverse and longitudinal orientations, which are referred to as vertical stiffeners, or in both directions.
- At the support regions, a certain portion of the web acts as column i.e., compression member and there is a possibility of web buckling and hence bearing stiffeners are required.
- If concentrated loads are also acting on the girder then intermediate stiffeners are required to prevent the web from buckling.
- Longitudinal stiffeners are provided to improve buckling strength of the web.
